LEAF-TURNER FOR BOOKS.

SPECIFICATION forming part of Letters Patent No. 739,308, dated September 22, 1903. Application filed May 23, 1903. Serial No. 158,382. (No model.)

T0 (1% whom it may concern:

, Be it known that we,WALTHER GUMNITZ,residing at Dresden-Briesnitz, and .MORITZ J U- LIUS SEYDEL, residing at Dresden-Gotta, Germany, both subjects of the Emperor of Germany, have invented certain new and useful Improvements in Leaf-Turners for Books, of which the following is a specification.

Our .invention relates to implements for turning over the leaves of books and the like, and has for its object to provide a simple and inexpensive yet efficient device for the aboveindicated purpose.

The invention will now be described with reference to the accompanying drawings and then the features of novelty will be pointed out in the appended claims.

Figure l is a side elevation of the improved Fig. 2 is an end view thereof, and Fig. 3 is a partial longitudinal section on line 3 3 of Fig. 2.

The leaf turner comprises a handle A, which is substantially straight and may be ornamented, if desired. At one end this handle is enlarged, as shown at A, and upon this enlarged end isfitted a ring or disk B of rubber or other flexible material. This ring or disk, which forms a lifting-disk, is preferably corrugated upon its periphery, and it is best to dispose the corrugations at an angle, as shown. The ring or disk B is secured to the handle in any suitable manner-for instance,

by means of a metallic washer O and a screw D. This screw is preferably extended to form a weight E.

In using the device it is held by the handle A andthe lifting-disk B is allowed to rest on the leaf of the book near the edge. The weightE contributes to produce the necessary friction between the paper and the liftingdisk. When the latter is revolved, it will first buckle and then raise the uppermost leaf of the open book. It is preferable to hold the handle A at an angle'to the plane of the book, so that the edge of the lifting-disk where it is in contact with the paper will be bent sidewise, and this facilitates thelifting action. 1

It will be understood that the peripheral portion of the lifting-disk is free, so that it may properly engage the paper.

We claim as our invention- 1. Animplement forthe'purpose described, comprising a handle, a lifting-disk securedthereto, and a weight arranged on the side of the lifting-disk opposite to the handle.

2. Animplement fonthe purpose described, comprising a lifting-disk, a handle on one side thereof and a weight on the other side of the lifting-disk, said weight having a projection extending into the handle, to hold the parts together.

3. An implement for the purpose described, comprising a handle enlarged at one end, a lifting-disk made of flexible material and arranged in engagement with the enlarged end of the handle, and a weighted securing device extending through the lifting-disk into the handle.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
